- (15 min) Give students the Progress Quiz (no review today)

Progress Quiz Scoring Rubric:- 9-10 points: Student who has grasped the concepts in lessons 1-9.
- 7-8 points: Average student. Should work on concepts in problems missed.
- 5-6 points: Student who has missed some major concepts. Needs help in areas not understood. What you do here depends on whether the student's work exhibits sloppy computation or misunderstood concepts.
- Below 5: a 'lost' student. Probably has not been turning in homework. Retention in this program (or steps to get homework turned in) should be a discussion topic with student and parents. Remember, this is the student that you can damage mathematically by dragging them through more complex topics in the months to come.

- (10 min) Introduce negative numbers:
- Draw this number line on the board:

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9

- Pass out the Negative number handout and follow the discussion and examples in the handout.
- Get students to come to the board to solve these problems:
- -2 + 8 (when results are positive, get students to put "+" signs on them)
- +5 - 10
- +2 - 5
- -4 - 3

- Draw this number line on the board:
